Minimal pico(rp 2040) template

Most 'templates' for the raspberry pico are rather involved and import many dependencies you might not want.

This template aims to include only a couple of crates that I considered absolutely needed (if you don't want to write a bootloader yourself that is). The end result should be a blinking LED.

The template is constructed to be used for a single pico, which is directly flashed over a usb connection.

To install this template run:

git clone https://github.com/emiongit/template_rp2040
cd template_rp2040
rustup target install thumbv6m-none-eabi
cargo install --locked elf2uf2-rs

If you want to run your project use:

cargo r -r
# or
cargo b -r && elf2uf2-rs -d target/thumbv6m-none-eabi/release/bin

Make sure your pico is connected to your pc and ready to be flashed (connected while pressing the BOOTSEL button).

This template assumes that you have a LED connected at gpio20 You can change that in the src/bin/bin.rs file.

Also if you are using a pico (H) and not a pico W(H) then you can also use the onboard LED. See the comments in the bin.rs to change to the onboard LED!
